To all whom it may concern: I

Be it known that I, FRIEDRICH BpLEG, chemist, a subject of the King of Wiirtemberg, residing at Oannstatt, in the Kingdom of Wiirtemberg, Germany, have invented certain new and useful Improvements in Processes for the Preparation of Water-Soluble Vaseline; and L- do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

-'I'he object of the present application consists of a process for the preparationvof water-soluble vaseline and of vaseline capable of being com ounded with-water for technical and me lcinal purposes.

For the preparation of the vaseline watersoluble mineral oils are made use of as a basis, which oils have been made water-soluble in the manner set out in detail in my application Serial N 0. 126,273. It may be stated here brief that the mineral oils mixed with crude rosin-oil first undergo a washing and treatment with direct steam and are then mixed with an excess of caustic alkali solution. Then thealkaline mixture of oil after separation of the rosin-soap lye is subjected to an oxidation process by the introduction of air under pressure or ozone and finally subjected tosa shorter or longer treatment under pressure of one to one and a half at mospheres at temperatures corresponding to this steam-pressure. Of the mmeral oils rendered water-soluble in this manner about ten to fifteen per cent. is mixed at the lowest possible temperature (from 40 to Celsius) with melted vaseline and the mixture allowed to cool with constant stirring. -There is obtained in this manner a vaseline which can be easily dissolved in water or canbe mixed easily therewith, whereby for certain purposes a great saving of vaseline is obtained. v

' Instead of using water-soluble mineral oils as the basis for mixture with the vaseline there may advantageously be employed wa- 3 0 ,ter-soluble clear rosm-o1ls or rosm-o1l watery solutions. These latter are obtained by boiling the crude rosin-oil with excess of caustic alkali solution with the application ofdirect steam and subjecting the alkaline rosin-oil mixture to a further treatment with vaseline, which consists 1n intimately mixing vaseline and ten to fifteen per cent. of watersoluble mineral oil.

3. The process of preparing water-soluble vaseline, which consists 1n intlmately mixing withmelted vaseline ten to fifteen per cent. of water-soluble oil at a low temperature and allowing to cool.

4; The process of preparing water-soluble hand in presence of two witnesses.
